Dog fecal material may constitute the dominant source of airborne bacteria

Bacteria from fecal material -- in particular, dog fecal material -- may constitute the dominant source of airborne bacteria in Cleveland's and Detroit's wintertime air, says a new University of Colorado Boulder study.

Prior parasitic worm infections may complicate TB therapy

Tuberculosis (TB) is a major threat to global health, taking the lives of more than a million people worldwide each year. Its greatest impact is often in the most impoverished places on earth, where patients frequently suffer from multiple chronic illnesses at the same time. In such situations, the question of whether each individual illness might make concurrent illnesses more difficult to treat becomes a critical issue both for specific patients and for general public health.

Insight into how HIV reservoirs may form

Much like cities organize contingency plans and supplies for emergencies, chronic infectious diseases like HIV form reservoirs that ensure their survival in adverse conditions. But these reservoirs-small populations of viruses or bacteria of a specific type that persist despite attack by the immune system or drug treatment-are not always well understood.

Harmless bacteria re-engineered to fight a deadly strain

Scientists in Singapore have re-engineered a harmless strain of bacteria to fight another common, drug-resistant microbe that spreads in hospitals and is deadly to patients with weak immune systems.

PERCH study to look at current and likely future causes of childhood pneumonia

Pneumonia kills more children around the world than any other disease, but the last major effort to study the causes of childhood pneumonia across many countries was conducted in the 1980's. This week, a groundbreaking new study called the Pneumonia Etiology Research for Child Health (PERCH) study gets off the ground.

Inexpensive microcalorimeters can quickly detect TB

Researchers have discovered a faster, cheaper method for the diagnosis of tuberculosis (TB). A major barrier in TB prevention, especially in developing countries, is that diagnosis is slow and costly.

Study confirms presence of bacteria linked with early childhood caries in infant saliva

New parents have one more reason to pay attention to the oral health of their toothless babies. A recent University of Illinois study confirms the presence of bacteria associated with early childhood caries (ECC) in infant saliva.

Alpha-synuclein protein key to Parkinson's has likely been mischaracterized

A new study finds that a protein key to Parkinson's disease has likely been mischaracterized. The protein, alpha-synuclein, appears to have a radically different structure in healthy cells than previously thought, challenging existing disease paradigms and suggesting a new therapeutic approach.

Starpharma starts bacterial vaginosis prevention study of VivaGel

Starpharma Holdings Limited today announced the commencement of its Phase 2 study of VivaGel for the prevention of bacterial vaginosis (BV), following receipt of ethics approval.

Fresh food for years with newly discovered natural preservative

Scientists have discovered a natural preservative capable of destroying a whole class of bacteria, including E.coli and listeria and now food can be made to remain fresh and last for years. There would also be no need to refrigerate produce treated with the preservative, called, bisin, which is produced by harmless bacteria.

Pyrazinamide inhibits trans-translation in Mycobacterium tuberculosis

For nearly 60 years, Pyrazinamide (PZA) has been used in conjunction with other medications to treat tuberculosis (TB), but scientists did not fully understand how the drug killed TB bacteria. PZA plays a unique role in shortening the duration of current TB therapy to six months and is used frequently to treat multi-drug resistant TB.

Study confirms ability of Tru-D device to decontaminate surfaces in patient rooms

In an original article coauthored by John M. Boyce, MD; Nancy L. Havill, MT; and Brent A. Moore, PhD, "Terminal Decontamination of Patient Rooms Using an Automated Mobile UV Light Unit", the research team from the Hospital of Saint Raphael and the Yale University School of Medicine ". . . demonstrated that an automated, portable UV light device significantly reduced aerobic colony counts on high-touch surfaces in patient rooms.

Researchers discover key reason why pyrazinamide shortens duration of TB therapy

Pyrazinamide has been used in combination with other drugs as a first-line treatment for people with tuberculosis (TB) since the 1950s, but exactly how the drug works has not been well understood.

NPL scientists mimick the ways viruses infect human cells and deliver genetic material

Scientists at the National Physical Laboratory (NPL) have mimicked the ways viruses infect human cells and deliver their genetic material. The research hopes to apply the approach to gene therapy - a therapeutic strategy to correct defective genes such as those that cause cancer.
